DISTRIBUTING MECHANISM OF TYPOGRAPHICAL COMPQSING-MACHINES.

Application filed March 27, 1916.

To aZZ whom it may concern Be it known that I, CARL HUnnLnisnn, acitizen of the United States of America, residing at Chausseestrasse 23,Berlin, Ni i, in the Empire of Germany, have invented new and usefulImprovements in the Distributing Mechanism of TypographicalComposing-Machines, of which the follow ing is a specification.

This invention relates to typographical composing machines such as thoseknown commercially under the trade mark Linotype, and particularly todistributing mechanism therefor of the kind described in Letters PatentNo. 1142222, which is used for separating matrices according to font inconnection with machines having several magazines and employing matriceshaving font-distinguishing notches in their feet. The inventiondescribed in the above-mentioned patent, provides, in addition to theusual three distributer screws adapted to engage the two upper and oneof the lower ears of each matrix while the latter is being propelledover the font-distinguishing bridges, a fourth distributor screw adaptedto engage the second lower ear of each matrix, and gripped or mutilated.over those portions o it which coincide with the spaces between thebridges, by which means the matrices were maintained in correct positionwhile traveling over, and allowed to drop freely between, the bridges.In the known constructional form of this arrangement, the fourth screwhas been mounted in a pivoted frame capable of being rocked away topermit the interior of the font separator, namely, the distributor rail.the matrices suspended thereon and the bridges, to be inspected. Inpractice, however, inconvenience has arisen through the continuedoperation of the distributor when the fourth screw is so rocked out ofits operative position, by reason of matrices falling away from the fontseparator, or getting out of proper position. g

According to the present invention, such inconvenience is avoided byproviding means for stopping the operation of the font separator as soonas the fourth screw is rocked away.

The accompanying drawings illustrate a constructional form of thepresent invention as applied to the font separator of a ma- PatentedJan. 36), 1917.

means. 1

The frame 1 of the separator is of l znown construction, and carries thefont-distinguishing bridges (not shown in the drawings), as well as thedistributor screws, the lower mutilated screw 2 being arranged inbearings 8, which are pivotally connected at 4 to the frame 1. One screwof the font separator is driven by a shaft 5 which is geared with theother screws by means of pinions (3. The shaft 5 has a clutch ring 7axially movable but angularly fast on it, with which ring a lever 8engages. The lever 8 is connected by means of arod 9, with a lever 10which rocks about a fixed pivot 11, and has a cam surface 12 (Fig. 3)abutting against a stop 13 fast to the adjacent bearing 3 of the screwThe shaft 5 is also erovidcd with a loose pulley I i which is drivenfrom the main driving shaft of the machine by a belt 15 and which can becoupled and uncol'lpled from the shaft 5 by the clutch ring '7.

When the screw 2 is in the operative position, as shown in Fig. 1 and infull lines in F 2, the stop 13 bears against the lever 10 and holds itin its leftmost position (Figs. 1 and thereby, through the rod 9 andlever S, maintaining the clutch ring '7 in engagement with the pulley14, against the action of a spring 16 constantly tending to throw theclutch out, so that the shaft 5 is.

driven and the separator operates in the known manner. When, however,the screw 2 is rocked, by means of the handle 17 provided for thatpurpose, into the position shown in dotted lines in Fig. 2 in which thedistributor rail 18 and interior 'of the font separator are open toinspection, the stop 13 is moved out of contact with the lever 10 thuspermitting the spring 16, acting through the rod 9 and lever 8, todisconnect the clutch 7 from the pulley 14, whereby the separator isstopped. On the return of the screw 2 to its operative position the stop13 glides over the cam surface 12 of the lever 10 and restores thatlever to its leftmost position, throwing in the clutch and causing thenormal operation of the separator to be resumed.

Having described my invention, I declare that what I claim and desire tosecure by Letters Patent is 1. In a typographical composing machine, thecombination with a distributer rail, four distributer screws adapted topropel matrices along the said rail, and drivin means adapted to rotatethe said screws, 0 means whereby one only of the said screws can bemoved out of its operative position, and means adapted to disconnect thedriving means and screws when the said screw is so moved. 7

2. In a typographical composing machine, the combination with adistributer rail, four distributer screws adapted to propel matricesalong the said rail, and driving means adapted to rotate the saidscrews, of means whereby one only of the said screws can be moved out ofand into its operative position, and means adapted to disconnect andconnect the driving means and screws when the said screw is movedrespectively out of and into the said position.

3. In a typographical composing machine, the combination with adistributer rail, four distributer screws adapted to propel matricesalong the said rail, and driving means adapted to rotate the saidscrews, of a pivot for the bearings of one of the said screws, the saidbearings, and means adapted to disconnect and connect the driving meansand screws when those bearings are rocked about the pivot to move therespective screw out of and into its operative position respectively.

4. In a typographical composing machine, the combination with adistributer rail, four distributer screws adapted to propel matricesalong the said rail, and driving means adapted to rotate the saidscrews, of a clutch adapted to establish and disestablish drivingconnection between said driving means and screws, a pivot for thebearings of one of the said screws, the said bearings, and means adaptedto open and close the clutch when those bearings are rocked about thepivot to move the respective screw out of and into its operativeposition respectively.

5. In a typographical composing machine, the combinationwith adistributer rail, four distributer screws adapted to propel mat ricesalong the said rail, and driving means adapted to rotate the saidscrews, of a clutch adapted to establish and disestablish drivingconnection between said driving means and screws, a pivot for thebearings of one of the said screws, the said bearings, and a springconstantly tending to open the clutch and adapted to be released whenthe said bearings are rocked about the pivot to move the respectivescrew out of its operative position.

6. In a typographical composing machine, the combination with adistributer rail, four distributer screws adapted to propel matricesalong the said rail, and driving means adapted to rotate the saidscrews, of a clutch adapted to establish and disestablish drivingconnection between said driving means and screws, a pivot for thebearings of one of the said screws, the said bearings, a springconstantly tending to open the clutch, and a lever adapted to close theclutch against the action of the said spring when the said bearings arerocked about the pivot to move the respective screw into its operativeposi tion.

7 In a typographical composing machine, the combination with adistributer rail, four distributer screws adapted to propel matricesalong the said rail, and driving means adapted to rotate the saidscrews, of a clutch adapted to establish and disestablish drivingconnection between said driving means and screws, a pivot for thebearings of one of the flopiel of this patent may be obtained for fivecents each, by addressing the "Commissioner of Patents.
